Intake of iron, zinc and iodine in 28 Ethiopian children living in Wonji Shoa Sugar Estate, assessed by duplicate portion technique

  In the present study, duplicate diets (four-day survey) of 28 Ethiopian children were analysed for iron, zinc and iodine. The mothers of the children filled out a food frequency questionnaire describing general intake of local food ingredients. The average daily intake of zinc was found to be 5.7 ± 5.2 mg, while the daily intake of iron and iodine was 52 ± 43 mg and 0.13 ± 0.10 mg,...

The correlation of chemical characteristics and UF-Resin ratios to physical and mechanical properties of particleboard manufactured from vine prunings

  In this study, the relationship between chemical characteristics of chips, UF-Resin ratios and physical, mechanical properties of particleboard manufactured from vine prunings was investigated. Before particleboard manufacturing, the chips produced from vine prunings were subjected to chemical pre-treatment such as cold water treatment (CW), 1% NaOH treatment (N) and 1% CH3COOH treatment (A). FTIR...

Investigation of the efficiency of the furniture industry in Turkey

  Development of a country depends on the efficiency of the production in each sector. The efficiency in the sector is brought about mostly by the use of modern technology and effective management techniques. Prior to the establishment of an organization, it is necessary to know whether it will be economically viable, the cost of the facilities and the goods to be produced, and possibility of making profit from...

Geomechanical properties of construction stones quarried in South-western Turkey

  Geomechanical properties of natural stones have a crucial importance when stones are used for constructing modern structures and buildings. Therefore, field and laboratory studies are indispensable to investigate the stone quality for purposed structure. Denizli and Antalya surroundings in South-western Turkey have large natural stone reserves and more than 80 quarries operated actually. They export natural...

Effects of glass spheres on the mechanical characteristics of NR-SBR type elastomers

  In this study, the effect of glass spheres on the physical and mechanical properties of NR-SBR elastomer-based shoe sole material was investigated. In the experiment, the blend of natural rubber (NR-RSS3) and styrene butadiene rubber (SBR 1502) in certain amounts were considered to use. Therefore, 2 newly developed glass sphere blends were prepared and tested. The new blends exhibited much better mechanical...

Determination of strain accumulation in landslide areas with GPS measurements

  People have suffered from past to present from natural events such as earthquakes, landslides, avalanches and floods that are called disasters. It is necessary to monitor ground movements in areas where disasters like landslides may occur in order to reduce and mitigate effects of such disasters which put people’s lives at risk. Space-based positioning technologies including global positioning system...

Paleomagnetic studies on Anatolian plate and some geodynamic implications

  The study area is located in some areas in Anatolian plate (Afyon, NevÅŸehir, Hasandağı-Melendiz Dag, Karadag, KaracadaÄŸ, Karapınar sites). For paleomagnetic study, it was taken oriented 324 core samples from 36 locations. First of all, natural remanent magnetizations of all samples were measured by Spiner magnetometer and then thermal demagnetization treatment was applied to each sample by...

Adaptive neuro fuzzy inference system for estimating particle diameter of soils in micro structure for varying quantities of sodium hexametaphosphate

  In the present study, 0, 10, 20, 30, 40, 50 and 60 g. Sodium hexametaphosphate (NaPO3) suspensions were prepared for hydrometer tests. After the completion of the tests, the particle diameters of the soil were calculated for each hydrometer reading at time intervals of (0, 1, 2, 5, 10, 15, 30, 60, 120 and 260 min). A model was developed using an adaptive neuro-fuzzy inference system (ANFIS) to predict the...

Monitoring land use changes in tourism centers with GIS: Uzungöl case study

  In Turkey, highlands have been used as venues for livestock and summer recreation for many years. Today, however, they are subject to alternative tourism and recreation activities, which dramatically change the nature in these regions. Because of natural beauties, “Touristic Centers” for eco-tourism have started rapidly in these places for the last three decades. Uzungöl, which belongs to...

Developing the basics of pavement management system in Besiktas district and evaluation of the selected sections

  Pavement management is in a broader sense, a working program that involves all the procedures of planning, programming, designing, building, maintaining, and rehabilitation. Pavement management concept is first introduced in the 1960’s to ensure the best use of existing resources. Today many corporations in USA use managements systems either developed by themselves or modified to fit their climate,...

Lead levels in some edible vegetables in Lagos, Nigeria

  This study was carried out to investigate the level of lead in six edible vegetables from two popular markets and farms in Lagos metropolis. Total acid leaching digestion method was employed and determination of the lead was done by atomic absorption spectrophotometry (AAS). All the vegetables were analyzed in the forms in which they are normally consumed. The concentration of lead obtained ranged from 0.00...
